Overall DNS response rate was 98.7%, with 301 of 305 nodes returning a valid resolver response and a median lookup time of 14 ms. The rate sits just below the 99% threshold and is noted as an observation.
twitter.com DNS lookup performance by network
DNS response rate counts probes with a DNS response and measured lookup time. P50 is the time at or below which half of responding lookups completed; a response need not contain an address and does not establish propagation or poisoning.

Key findings
- Overall DNS response rate was 98.7%, below the 99% threshold, leaving 4 nodes without a valid resolver response.
- Telecom had the lowest response rate at 97.5% (119/122); Unicom and Mobile both reached 100%.
- DNS lookup times were similar across carriers, with medians of 14 to 15 ms; the overseas group was faster at a 2 ms median and 7 ms average.
- Eleven distinct resolved addresses were observed, which reflects answer diversity only and does not establish whether resolution was correct.
Improvement recommendations
- The DNS response rate is 0%, below the 99% review threshold. Retest the unanswered probes and verify the authoritative DNS service, query type, and record only if failures persist.
